Dry mixing of spice powders - investigation of effect of powder properties on mixture quality of binary powder mixtures
Dry mixing of binary food powders was conducted in a 2L lab-scale paddle mixer. Different types of food powders such as paprika, oregano, black pepper, onion powder and salt were used for the studies. A novel method based on a digital colour imaging system (DCI) was developed to measure the mixture …

Discrete element method based scale-up model for material synthesis using ball milling
Mechanical milling is a widely used technique for powder processing in various areas. In this work, a scale-up model for describing this ball milling process is developed. The thesis is a combination of experimental and modeling efforts. Initially, Discrete Element Model (DEM) is used to describe …

Air slide basic modelling
… pipe is efficient only if it is kept full of powder - the feeding silo acting more as a buffer for the stand pipe. Their concept was implemented in practice during the tests conducted at POSTEC by monitoring the weight of material in the stand pipe and the flow rates of alumina in real time by …
